Tesla has built more than 5,400 Superchargers since 2012. It’s an impressive feat until you consider that the company plans to double that number to total more than 10,000 globally by the end of 2017.

The electric automaker noted that it has also built more than 9,000 Destination Charging connectors in the same amount of time. Unlike traditional Superchargers, Destination Chargers use Tesla Wall Connectors, are a bit slower and are largely meant for overnight stays at hotels or resorts.

Come the end of 2017, Tesla aims to have roughly 15,000 Destination Chargers up and running around the world. Tesla said it’ll be increasing the number of Superchargers in North America by 150 percent and will be adding more than 1,000 in California alone.

Furthermore, charging stations along busier travel routes will be expanded to accommodate several dozen Superchargers. Some will even be built further off the highway to allow local users to charge quickly without having to deal with as many out-of-towners.

The expansion is more or less a requirement if Tesla hopes to push forward its electric initiative. Congestion at Supercharging stations is already a problem in some areas and things are only going to get worse when the mainstream Model 3 arrives. By expanding the charging infrastructure now, Tesla is making room for the huge influx of cars that’ll be hitting the roads in the near future.
